Un-Default
One thoughtful-language check for every way you build.
Formerly Anti-Default. Same tool — the name shifted so it reads as undoing defaults, not opposing people. Old URLs under
darkai.ca/anti-defaultredirect here.npx anti-defaultstill works as an alias fornpx -y anti-default.
Un-Default reviews copy, docs, UI strings, and live pages for colonial defaults, gendered assumptions, ableist metaphors, and documented dogwhistles. It explains what it noticed and offers clearer alternatives.
No account. No AI required for matching. Open rules you can tune.

After Claude / Cursor writes UI copy
One command — skill + MCP + PR check. This is the habit that sticks:
npx -y anti-default init
Or install the Claude Code plugin from this repo’s marketplace:
claude plugin marketplace add NomadBuilder/anti-default
claude plugin install un-default@un-default
Paste-ready MCP JSON, Claude Project instructions, and a LinkedIn draft:
https://darkai.ca/un-default/for-agents/
Directory checklist: docs/PUBLISH-DIRECTORIES.md
Paste MCP config (Cursor · Claude Desktop · Claude Code)
{
"mcpServers": {
"un-default": {
"command": "npx",
"args": ["-y", "anti-default", "mcp"]
}
}
}
| Host | Where it goes |
|---|---|
| Cursor | .cursor/mcp.json (written by init) or Settings → MCP |
| Claude Desktop | Settings → Developer → Edit Config → claude_desktop_config.json (merge, quit, relaunch) |
| Claude Code | Plugin marketplace (above), or .mcp.json via init, or claude mcp add |

Add it in under a minute
npx -y anti-default .
That is the whole local setup. It prints findings and exits non-zero on clear hits. Ambiguous or quoted matches stay advisory.
To pin it in a team project:
npm install --save-dev anti-default
Want the complete project setup?
npx -y anti-default init
init adds an ignore file, changed-files GitHub workflow, Cursor + Claude
skills, .cursor/mcp.json + .mcp.json, Claude/Cursor after-edit hooks,
CLAUDE.md instructions, and inclusive-check / inclusive-fix scripts.
Existing files are never overwritten. Hooks surface hard findings back to the
agent after Edit/Write so Claude keeps checking even when nobody remembers.
AI-copy habit (definition of done)
npx -y anti-default fix . # safe 1:1 autofixes only
npx -y anti-default . # remaining findings
Agents should not mark UI/docs work done until hard findings are cleared or explicitly marked fine in context. Soft/coded hits stay advisory.
# Preview autofixes without writing
npx -y anti-default fix . --dry-run
# Intentional language — suppress locally + share structured feedback
npx -y anti-default feedback --kind fine_in_context \
--rule guys-generic --match "guys" --context "…snippet…" \
--note "Quoted lyric" --open-issue
MCP server
npx -y anti-default mcp

Ignore what doesn’t matter
Commit a .undefaultignore so day-two noise doesn’t drown the team (example):
node_modules/
vendor/
*.min.js
rule:guys # turn off one rule for this repo
GitHub Action
Keep inclusive language in the PR loop. This scans only changed files, fails on clear new findings, and leaves a checklist comment:
# .github/workflows/un-default.yml
name: Un-Default
on: [pull_request]
permissions:
contents: read
pull-requests: write
security-events: write
jobs:

Prefer SARIF for Code Scanning? Set format: sarif and output-file: un-default.sarif. Full inputs: action.yml.
Agent skill
npx -y anti-default init installs .cursor/skills/un-default/SKILL.md — the
definition-of-done workflow for AI-generated copy: fix → scan → ask or
feedback → re-scan.

Use it as a library
The npm package has no runtime dependencies and exposes the same analyzer used by the CLI and web app:
import { analyzeText, LANGUAGE_RULES } from "anti-default";
const result = analyzeText("Welcome, you guys.");
console.log(result.findings);
Chrome extension
Same rules as the app — on the page you’re already looking at.
Runs offline from a bundled rule list. No tracking. No AI calls.
Dev / unpacked: npm run extension:pack → Load unpacked → extension/ · details in extension/README.md
Web app — try, learn, tune
- Review — paste, upload, or scan a URL; export Markdown, CSV, or a checklist
- Swap — turn one phrase into clearer alternatives
- Dogwhistles — learn what a phrase can signal and when context matters
- Rules — tune the open rule catalog for your project
npm install && npm run dev # localhost:3000
Why teams reach for it
- Before publish — catch defaults in marketing, docs, and product copy
- In the PR — Action + SARIF/JSON so machines and humans both get a signal
- On the live page — extension for writers who never open a terminal
- Without a lecture — suggestions are invitations; context always wins
Every suggestion cites the style guides and references behind it → /sources
Customize & self-host
- Tune in the UI: /rules · edit code:
src/lib/rules.ts - Practice corpus:
npm run corpus - Static export:
npm run build→out/
Subpath (DarkAI):STATIC_EXPORT=true BASE_PATH=/un-default npm run build
Production lives at darkai.ca/un-default and is also vendored in DarkAI.
